To 'all 'whom it may concern:

Be it known that' I, ALEXANDER M.A Gow, a citizen 4of th.United States, and resident of Duluth, county of St. Louis, and State of Minnesota, have invented certain new and .useful 'Improvements in Li uid-Measuring Apparatus, -of which the ollowing is a seciicatio'n, and which are illustrated in t e accompanying drawings, forming a part The invention relates yto automatic devices for measuring liquids, its'object being tg.

vsim lify and cheapen devices of this whi e securing eiliciency in operation.

The invention consists 'in Va device such as is hereinafter described, and -as 'diagrama'tically illust-rated 1n the accompanying dnwings, in Wh'ich l Figures 1', 2, i3. and 4 show the apparatus' in vertical section .and lit-differentstages in the cycle ofiitsoperation;` and Fig. -5 is. a sectional view of a modified form of the,

transferring connection between the two compartments' ot the apparatus. L

In -the .-simplolform. .'m Jwhich the device is shown, it comprises aftank 1, divided by ahoriz'ontalpartition 2'. into a measuring compartment 3, anda receiving and regulating compartment 4. These compartments so 5 passinglth'rough the partition 2, and com-A are united by means ofan S-shaped pipe prising an upper or receivin Y leg 5, a connecting leg, and a ylower-or ischarge leg 7.

The pipe' `for delivering liqluid to the aparatus is shown at 8, and as branches 9 eading to the` compartment 4, and 10 leading to the compartment'S, These'branches are. proyided, respectively, with the manu` ally-controlled valves 11 and 12, and in thc branchxlO there is placed an additional valve 13,-controlled by a iloat 14 in the compart- 'ment 4, the float lever being connected with the ,vave-s'tem by 'means of the rod 15. 4,5-

' 'uppexend o :6 thereis an overflow vent leading from the com artplent 4, on a level with the i) the leg 7 'ofthe connecting pipe.

At 17 there is shown a discharge Apipe v leading from the compartment 4, and regulatedby meansof a valve 18, which is shown as being manually controlled. '-A float 19 actuates a counter 20 for registering the number of operations of the apparatus.

`being open .at both ends.

fair-is trapped inthe connecting leg At 21, 22 and 23 are -shown 'drain pipes 55 leading, respectively, from thc lowe'i` ends of the legs '6 and?? of the connecting pipe and from the compartments 3.and 4. v'

The form of the transferring passage may bc varied. As shown in Fig. 5' this trans- 60 ferring device comprises a vert-ical pipe section 24, setting through the artition2 and ver the upper, end 0f this pipe Section .is placed a-bell 25, and its lower end is inclos'ed Within a cu.) 65 shaped trap 26.v AThe action is recisely t e same as in the form shown in `igs. l to 4,-.

the three elements constituting in effect the- 1' ffl l -The valve'all is now closed and thevalves 12 and 18'are' opened. As liquid isfdrawn-f, lf3 of through the pipe 17the levelin come;- partment 4 is lowered gradually, the float 80 14 drops down far enough to open the valve 143, as shown in 2. Liquid now entersI compartment 3, an .as it rises a volume of? s 5 andu 6. This anis com ressed gradua ly, lo'w- 85 ering the level of t e liquid in the intel-1` mediate legz6. The leg 5 is preferably made of greater. cross-sectional arca than the leg' 6, whereby the depression of the liquid in the latter leg is greater than the rise of liquid in the former. When the liquid has risen to such a height in compartment 3 that the hydrostatic head from its level to the level 1n le 5 is equal to the head from the j unctureov legs 6 and 7 to the top of leg 7, 95 as shown, respectively, at a, and b (Fi 3),

the apparatus isjust ready to disc arge from compartment 3 to compartment 4. A

`further rise of liquid in compartment 3 will cause a portion of the compressed air to escape into leg 7, thus reducing the pressure in le 6 as well as forcing water out'of leg 7.. his destroys the equilibrium, and the liquid in 'compartment 3 Hows freely into compartment 4, the pipe acting as a Siphon durin the latter part of the discharge, bringing the levelin compartment 3 to the open'end of the leg 5, whereupon air enters opening the valve 13 and recharging com-- partment 3, and repeating the cycle as bcfore. the lower compartment as rapidly as desired, it beingimportant only, when the discharge is continuous, that it be not too rapid to permit the actuation of the ioat 14. The float 19 actuates the 'registering device 20 at each filling of compartment 3; the capacity of one discharge being known, the aggregate quantity of liquid passing through the apparatus is determined.

. Because of the simplicity of the apparatus and its freedom from'moving parts, it bccomes valuable for use not only in measurlng water but acids and corrosive liquids,

and its operation is free from danger of stoppage or cloggingl by dirt, chips, or other extraneous substances which the liquid may -shown as being in S form, alent design may be used.

The apparatus is serviceable in various situations, as, for example, in connection with the open or vacuum type of feed water heaters.
